AC Milan captain Massimo Ambrosini has demanded teammates buck up their ideas after defeat to Atalanta.

The Rossoneri have lost their opening two games at San Siro, their worst home start in Serie A since 1930.

"We have a psychological block and have to give something more, on a physical and mental level, to emerge from this period," said Ambrosini.

"We aren't feeling the enthusiasm and are a little more worried than usual at the moment.

"This team can do well and the departure of so many players this summer must no longer be an alibi."
